RAZOR.

Specification of Letters Patent.

Application filed July 6, 1909.

Patented Apr. 11, 1911. Serial No. 506,102.

T0 all whom it may conccm:

Be it known that I, SAMUEL W. CHARLES, of the town of Palo Alto, countyof Santa Clara, State of California, have invented a new and usefulImprovement in Razors, of which the following is a specification.

My invention relates to a razor of the type in which the handle extendslongitudinally with respect to a blade provided with a guard and whichmay be automatically stropped.

The primary object of my invention is to provide a razor with a bladelongitudinally pivoted on a handle wi th means for correctly andautomatically stropping the blade which is provided with a guard andmeans for locking the blade rigidly on the handle and also for releasingthe blade for stropping.

The invention consists in the construction and arrangement of partswhich Will be more fully hereinafter speoified in preferred form.

In the drawings Figure 1. is a plan view of a strop and a razorembodying the l'eatures of my invention. Fig. 2. is a partiallongitudinal section through the center of the razor with the guard inposition against the blades. Fig. 3. is a partial end view showing theguard in position against the blades.

A are the two blades of the razor and are firmly held in position inbladc holdef B. Rigidly attached to blade holder B is a flanged pulleyC. Blade holder and pulley are revolubly attached to a spindle D.Spindle D is an extension of and is integral with handle E. Blade holderB and pulley 0 are retained in position on the spindle D by means ofsleeve F which is fastened to the spindle.

G is a locking sleeve, loose on handle and spindle, but with a limitedmovement.

II is a pin set rigidly into the spindle D with both ends projectingslightly therefrom to engage two diametrically opposite slots K in theinner surface of the locking sleeve G.

I is a locking pin and is set rigidly into the locking sleeve, one endprojecting' sufliciently to engage a hole made to receive it in thepulley C.

J is a helical spring the purpose of which is to force the lockingsleeve against the pulley.

P is a combed guard plate and is pivoted on handle E by means of pin Q.

R is a latch movably attached to guard plate P and furnished with twohooked fingers S which may be slipped over the corners of blades A.

T is a lug on latch R and serves as a handlc when the latch is operatcd.

U is a spring iastened to the guard at V and engaging with both ends thelatch R. Its purpose is to retain the latch in the position shown.

In the strop, Fig. 1, L are clamps, M is the strop, and N is a flexiblecord attached by its ends to the two clamps.

When the mechanism is in position for shaving, sec Fig. 2, the guardplate P is held firmly against the blades by the hooks S on latch R.Locking pin I in sleeve G engages its hole in the side of pulley C andis kept there by the action of spring J. Sleeve G is prevented fromrotating by the in H which engages the slots K. Thus the lflade-holder Bis fimnly locked to the handle E and the guard to the blades, the wholemechanism acting as a unit. When it is desired to strop the bladcs, theguard is released by grasping latch handle T and pulling the latch outuntil the fingers S are clear of the blade when the guard may be swungaway from the blades to the position shown in Fig. 1. Then the bladeholder B is released by draW- ing back the locking slceve G therebywithdrawing pin I from the pulley C. T0 prevent the sleeve G from beingsnapped forward by the spring J it is drawn back until it clears pin H,as in Fig. 1, and is then partly turned to dispose the pin H out ofalinement with the slots K, and the sleeve is held by the pin in theposition shown.

The razor is brought into position on the strop and the cord N woundonce around the pulley C as shown in Fig. 1. When the razor is movedforward and backward along the strop, the action of the pulley upon thecord is such that the blade is extended in a direction opposite to thatin which the razor is moving and is pressed against the strop. When theend of a stroke is reached and the rctum stroke is bcgun, the action ofthe cord on the pulley swings the blade into proper position the instantthe return stroke begins, thereby efiectually preventing any cutting ofthe strop. After the blades have been swung, the cord slidcs on thepulley for the entire stroke, the friction pressing each blade in turntightly against the strop.

and the pin H are in line and the sleeve snaps forward. The handle isthen turned relatively to the blade holder until pin I engages thepulley. Then the guard plate is swung about its pivot until it liesagainst the blades when by pulling out the latch and then releasing it,the blades Will be grasped by the hooked fingers S I have shown the cordN W0und once around the pulley but it may be wound more than once ifdeemed advisable. The pulley C is shown to be cylindrical but its facemay be of irregular outline.

'I do not desire to limit myself to the precise construction andarrangement of devices herein shown and described as it is evident thatmodifications may be made Within the scope of the appended claims.

Having thus described the nature and 0bjects of my invention and themanner of its operation, what I claim as new and desire A; to secure byLetters Patent, is

1. In a *razor of the class described, the oombination of a handlehaving a spindle projecting longitudinally from one end thereof, a bladeholder revolubly mounted on said spindle, means for locking said bladeholder to the handle, a pulley on the said blade holder for engagementby an operating cord, and a gnard pivotally 1nounted on the handle forangular movement toward and from the blade holder.

on said spindle and having a pulley, a sleeve mounted for longitudinalmovement on said handle, said sleeve and pulley having ooacting devicesto look them together, and said sleeve and spindle also having coactingdevices to look them together.

4. In a razor, the combination of a handle, a blade holder projeotinglongitudinally therefrom, and revolubly mounted thereo'n, said bladeholder carrying a pulley adapted to be engaged by an actuating cord, amember slidable on thehandle and having means to look the holder rigidlyto the handle, a

spring to move said member into locking position and means for holdingsaid member in retracted position.

5. In a razor, the combination of a handle, a pivot projectinglongitudinally from one end thereof, and carrying a radially projectingpin, a blade holder revolubly monnted on said pivot, and provided at itsinner end with a cord engaging pulley having in its end a seat, a sleeveto slide on the handle and carrying a longitudinally projecting pin toenter said seat in the end of the pnlley, said sleeve being recessed andhaving a longitudinal groove to receive said pin on the pivot wherebythe sleeve may be retained in retracted position, and a coil springwithin the recess in the sleeve and surrounding said pivot.

6. In a razor, the combination of a handle, a blade holder projectinglongitudinall therefrom, a guard to co-act With the blade in said holderand having its inner end pivoted to the handle, a slidable latch platehaving a slot and pin connection with the outer on free end of theguard, and formed with a finger pieoe, and with hook-shaped ends toengage the outer extremity of the blades, said latch plate being alsoformed With oppositely arranged apertured ears, and a spring wire fixedat its center to the guard and arranged transversely thereof, and havingits ends arranged in the'apertured ears on the latch plate.
